Right this moment, a brand new Bitcoin Enchancment Proposal (BIP) was launched, outlining a transparent plan emigrate Bitcoin to post-quantum (PQ) cryptography, with penalties for wallets, miners, exchanges, and holders who fail to improve.
The proposal introduces a phased plan to eradicate reliance on present ECDSA/Schnorr signatures, which can be weak to future quantum pc assaults that would break personal keys to steal bitcoin. The plan turns quantum safety into a tough incentive, “fail to improve and you’ll actually lose entry to your funds.”
“We search to safe the worth of the UTXO set and reduce incentives for quantum assaults,” the proposal said. “By no means earlier than has Bitcoin confronted an existential risk to its cryptographic primitives. A profitable quantum assault on Bitcoin would end in important financial disruption and harm throughout your entire ecosystem. Past its affect on worth, the flexibility of miners to offer community safety could also be considerably impacted.”
The proposal outlines three phases:
- Section A would prohibit sending bitcoin to quantum-vulnerable addresses, encouraging the adoption of the post-quantum tackle sort (P2QRH).
- Section B, anticipated to activate two years after part A, would make all ECDSA/Schnorr based mostly transactions invalid, successfully freezing any funds that haven’t been migrated.
- Section C, which stays elective and topic to additional analysis, might supply a restoration path with a proof of possession of a corresponding BIP-39 seed phrase.
The motivation behind the proposal is the accelerating progress in quantum computing. In 2024, NIST authorized a number of post-quantum signature schemes, whereas some specialists estimate {that a} quantum pc able to breaking classical encryption might arrive as early as 2027-2030. The proposal warns that roughly 25% of all bitcoin have uncovered public keys on-chain, making them weak to quantum theft.
By blocking new transactions to quantum-vulnerable addresses, the proposal goals to cut back the longer term assault floor with every new UTXO created. This transformation is designed to hurry up the adoption of post-quantum tackle codecs by making them the one legitimate choice going ahead. Given how lengthy Bitcoin upgrades take to totally implement, this strategy goals to push stakeholders to behave sooner.
